"It's Okay, It's Love" ended with high ratings and on an optimistic note. The drama, which attempted to portray mental illnesses in a sympathetic light, did just that, even if it occasionally confused viewers about the disorders it wanted to portray.

Mystery novelist Jang Jae Yeol, expertly played by Jo In Sung, was described in the drama's promotional material as being obsessive compulsive but he wasn't by any clinical definition. He did like his home neatly color coordinated but his compulsive behavior stopped there.

Some reviewers described him as schizophrenic. But while his character did have one dangerous delusion, seeing and talking to someone who did not exist, that person was created by his mind as a way to cope with a traumatic childhood. The character made sense most of the time and otherwise was well grounded in reality.
